Rollover/compress log from ACTIVE process
I have some Solaris processes that run weeks at a time that create rather large log files that I would like to archive/compress daily. Instead of stopping the process, what can be done so that the log file is backed up and shrunk, but the process can still log to the open file handle without major interruption.

scanlogs
SCANLOGS(8) InterNetNews Documentation SCANLOGS(8)
NAME
scanlogs - Summarize and rotate INN log files
SYNOPSIS
scanlogs [norotate]
DESCRIPTION
scanlogs summarizes the information recorded in the INN log files which reside in the pathlog directory set in inn.conf (see newslog(5) for
further details about these log files). It is normally invoked by the news.daily(8) script which performs daily server maintenance tasks.
It invokes "ctlinnd flushlogs" to close the news and error log files, rename them to add ".old" to the file names and open fresh news and
error logs; the active file is also flushed to disk, along with the history database.
By default, scanlogs rotates and cleans out the logs. It keeps up to logcycles old compressed log files in pathlog/OLD (the logcycles
parameter can be set in inn.conf). scanlogs also keeps archives of the active file in this directory.
It invokes tally.control if newgroup.log or rmgroup.log exists in pathlog (see the control.log entry of newslog(5) for more information
about that).
scanlogs displays the contents of errlog and news.crit, if non-empty, and runs innreport to summarize the contents of news and news.notice,
and to update the unwanted.log file amongst other things (see more information about that in innreport(8)).
OPTIONS
Only one option is currently accepted:
norotate
Using this option disables the rotating and cleaning aspect of the log processing: the logs files are only scanned for information and
no contents are altered. If scanlogs is invoked more than once a day, the norotate option should be used to prevent premature log
cleaning.
FILES
See newslog(5) for the list of log files processed by scanlogs.
